Filter



T. C. EWELL FILTER v Filed Sept. 6, 1934 Thomas GiEu/QZQ/ INVENTOR ATTORN EY WITNESS:

Patented Mar. 17, 1936 PATENT OFFICE 3 Claims.

The object of this invention is to provide a device of simple construction which may be easily inserted in the water-circulating system of an internal combustion engine and will operate automatically to remove all scale and other foreign matter from the circulating water. A filter embodying the invention is illustrated in the accompanying drawing, and the invention resides in certain novel features which will be particularly defined in claims following a detailed description.

In the drawing:

Figure l is a side elevation of a filter constructed according to the invention.

Figure 2 is a longitudinal section of the same.

Figure 3 is a section on the line 3-3 of Figure 2.

The reference numerals I, 2 indicate the opposed ends of hose sections through which the cooling medium flows from the pump to the radiator. Ordinarily, the hose is continuous but in the practice of the present invention the hose is cut and a short pipe 3, 4 is inserted in the respective ends and secured by hose clamps 5 of any approved design. The inner or opposed ends of the pipes are disposed obliquely across the axis of the hose, as shown at 6, and in parallel spaced relation to define a gap or open space I and across the end of the upper pipe is secured a brace 8. A fine mesh wire screen 9 is secured over said brace and the end of the pipe.

An expansion cylinder ll] of greater diameter than the pipes is secured around the opposed ends of the pipes in concentric spaced relation and houses the gap 7, and extends beyond the far side of the gap as shown in Figure 2, and a spout ll depends from the under side of the cylinder around an opening l2 in said side. Adjacent the lower end of the spout a cap I3 is formed or secured thereon to fit around the neck of a bottle like reservoir 14 to secure and support the reservoir, the end of the spout entering the reservoir and a gasket l5 being disposed between the bottle neck to seal the same.

The circulating water flows upward under pressure and its velocity is sufficient to carry it across the gap 1 to the upper pipe, but scale and other foreign matter will be arrested by the screen and by decreased velocity of the stream in the ex- 5 pansion cylinder and deflected into the housing and through the opening I2 to drop through the spout and collect in the reservoir. The device is exceedingly simple and inexpensive and may be fitted to or removed from the hose and it has no moving parts to get out of order. The reservoir is preferably of glass so that the quantity of material therein may be readily noted at any time, and it may be easily removed for emptying and replaced. 15

Having described my invention, what I claim is:

l. A filter of the type described comprising a. conduit having an oblique gap forming an outlet,

a sediment receptacle operatively connected to the conduit at the gap, and a screen in the oblique 0 gap inclined to the line of flow and adapted to direct sediment away from the gap and toward the sediment receptacle.

2. A filter of the type described comprising a conduit having an oblique gap forming an outlet, an expansion cylinder around the conduit housing the gap, a screen in the oblique gap inclined to the direction of flow and adapted to direct sediment away from the gap and toward the cylinder, and a sediment receptacle operatively connected to the cylinder.

3. A filter of the type described comprising a conduit having an oblique gap forming an outlet, an expansion cylinder around the conduit of greater diameter than the conduit and housing the gap, a screen in the gap inclined to the direction of flow and adapted to direct sediment away from the gap and toward the cylinder, a spout depending from the cylinder, and a sediment receptacle .on the spout.
